Training methods based on small- sided soccer game seem to promote greater physiological and tactical benefit for soccer players because they have more specific features to the game. Thus, the aim of this study is to analyze the physiological, biochemical, autonomic and neuromuscular parameters in time of effort and its dynamics during the process of recovery in four small- sided games. Taking part in the study are twenty-six professional's women soccer players. During and after the sessions of small- sided games, the heart rate variability (HRV) will be evaluated and blood samples will be taken before, immediately, 24h, 48h and 78h later for biochemical analysis, in addition to lactate concentration ([Lac]) and perception exertion (PSE) at specific times. Before and after the sessions, the Twitch Interpolation technique will be applied to evaluate the central and peripheral fatigue. The small- sided soccer games will be fully recorded by digital video cameras positioned at specific points of the field and the tracking is done through Dvideo® software. The sample size is calculated using G * Power 3.1 software, assuming the statistical power of 95% with a 0.05 significance level. Analysis of variance (ANOVA-TwoWay) will be used to compare the blood responce and central and peripheral activation. Possible associations between changes in investigated parameters and the performances in each small- sided games will be checked with the Pearson correlation test. The level of significance will be pre-set at p <0.05.
